ABSTRACT:
The invention relates to a hologram that enables two or more different images to be simultaneously reconstructed even in a state where the hologram is fixed in terms of relative position with respect to an eye, and a holographic viewing device that incorporates it. The hologram14is fabricated by applying Fourier transform to a plurality of input image to obtain a plurality of corresponding Fourier transform images13-1, 13-2and arraying the Fourier transform images13-1, 13-2on the same plane according to a given two-dimensional array principle into a computer-generated hologram. When a plurality of point light sources231to239located behind the hologram14are viewed through the hologram14, a plurality of images are simultaneously and parallel reconstructed (28) in correspondence to the array positions of the plurality of Fourier transform images.
